Filed: 1988-03-25
Abstract: PURPOSE:To reduce the concentration of compressive stress at an end of tapered part and to enhance the reliability of mechanical strength, by a method wherein the slope of a split tapered fitting is smaller than that of the tapered part. CONSTITUTION:A supporting device comprises a fiber reinforced plastic rod 1 which is provided with a tapered part 1a in a circular frustum, with an end thereof wider than the other. The device has its reinforcing fibers aligned in an elongated direction, and a split tapered fitting 2a which is tightened and fitted in the tapered part 1a. the slope of the taper of the fitting 2a is smaller than that of the rod 1. After tightening the fitting 2a, the compression displacement of the tapered part 1a varies depending on positions thereof. Since the average compression displacement of the tapered part 1a is equal to that of a conventional one, the tapered part 1a is never drawn out from the joint fitting 2. Moreover, since the compression displacement of a taper joint 1c is set smaller than that of the conventional one, the tapered joint 1c achieves reduction of concentration of the compressive stress. Therefore, reliability in mechanical strength of the device is enhanced.

Filed: 1990-03-20
Abstract: PURPOSE:To excellently fill up a through-hole by arranging a grid plate provided with a gap for passing the sputtered particles between a target and a wafer and impressing a voltage between the grid plate and target. CONSTITUTION:A grid plate 19 is arranged between a target 17 and a wafer 16 in a sputtering chamber 10, the wafer 16 is supported by an insulating member 15, and the grid plate is grounded. The chamber 10 is evacuated by a cryopump 12, gaseous Ar is introduced from an inlet 13, and a negative voltage is impressed on the target 17 from a power source 18. Consequently, the gaseous Ar is ionized between the target 17 and grid plate 19 and converted to plasma, and the Ar ion in the plasma is injected into the target 17 surface to liberate the sputtered particles. Most of the sputtered particles are passed through the gap of the grid plate 19 and deposited on the wafer 16 to form a film. As a result, the through hole is excellently filled up, and the wafer 16 is not contaminated with impurities and plasma.

IPC: F16H61/06
Filed: 1987-03-25
Abstract: PURPOSE:To make it possible to reduce overshoot pressure by providing a difference in pressure receiving area to a spool in a flow detecting valve so as to increase the returning speed of the spool after completion of filling. CONSTITUTION:The pressure receiving area A2 of the left end of a spool 21 differs from the pressure receiving area A1 of an oil chamber 25 such as A2>A1 and A2=2A1. Denoting the pressure upstream of an orifice as P1 and the pressure downstream of the orifice as P2, the force acting upon the left end face of the spool 21 is A2P2 while the leftward force effected by the hydraulic pressure in the oil chamber 25 is A1P1. Accordingly, a rightward force F is exerted to the spool 21 in the direction in which the spool 21 is closed. Accordingly, after completion of filling the spool 21 is returned by a force which is obtained by adding the force F due to the difference in the pressure receiving area to the returning force of a spring 22 so that the spool may be closed at a high speed, thereby it is possible to reduce overshoot pressure.

Title: Deep groove machining cutter
Inventor: UMEO KOUJI
IPC: B23C3/30
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To smoothly apply fine and deep groove machining and prevent chip clogging occurring in the gap between a cutter and a work at the time of machining by setting the edge width in the range shallower than a chip pocket thicker by a specific size on one side than the thickness on the inner side (no- edge section). SOLUTION: A cutter main body 1 has a flank backward in the cutting direction from a cutting edge 2, and its shape is continued with the roundness 6 of a groove bottom between a chip pocket 5 and a cutting face 7 from a heel 4. The roundness 6 of the groove bottom is a circular arc with the radius of 2 mm or below. Since the value of the radius is reduced, the volume of an edge section is increased, and the rigidity of a cutter is increased. The thickness of a no-edge section is made thinner by 0.02-0.3 mm on one side (b) than the thickness (t) of 2 mm or below of the cutting edge 2. Chip clogging can be prevented at the time of groove machining due to the heterogeneity of the gap between a metal saw and a work.
